Highlights:

• Strategic Agreement represents combined total project consideration of up to CAD $61.5 million consisting of cash payments to Skyharbour totalling $10.0 million, additional consideration of $8.0 million payable in cash and shares before year end, and expenditures and cash payments totalling up to $43.5 million for Denison to acquire between a 20% and 70% ownership interest over seven years in the claims making up Russell, with Skyharbour owning the remaining interests.

• Denison (TSX: DML; NYSE American: DNN), a leading uranium mining company with a market capitalization of over $3 billion, is developing the Wheeler River Project (‘Wheeler River’), which shares a 55 kilometre border with Russell. Denison is an existing, large corporate shareholder of Skyharbour and now joins the Company as a strategic, active, funding partner at Russell.

• The Project has been divided into four different joint ventures, including Russell Lake (‘RL’), Getty East, Wheeler North, and the Wheeler River Inlier Claims, of which Skyharbour will retain initial ownership interests of 80%, 70%, 51%, and 30%, respectively. Denison can then earn up to a 70% interest in the Wheeler North and Getty East properties through option agreements.

• The geological teams of Denison and Skyharbour have begun working cooperatively to advance and unlock value across the joint ventures, employing top-tier exploration and development expertise in the region.

• Denison has committed to a minimum of $4 million in exploration expenditures over the first two years at Wheeler North and Getty East combined, as well as agreeing to fund to maintain its pro-rata 20% participation interest in the RL claims through 2029 up until such time that total exploration expenditures on the property reach $10 million.

• Skyharbour will remain operator with an 80% ownership interest at the RL claims comprising over 53,192 hectares of the original 73,314 hectare Russell Lake Project. The Company will also act as operator during the first earn-in at Getty East with Denison sole funding the exploration in order to fulfill the earn-in option criteria.

• Skyharbour is well funded going into 2026 with over $11 million in the treasury. The Company will also generate revenue from its operator fee at the McGowan Lake exploration camp at the Project, as well as from cash and share payments from other option earn-in partner companies.

• Skyharbour will continue to directly advance its high-grade Moore Uranium project as well as the RL claims at Russell, while partner companies fund exploration at some of the Company’s other projects.

Jordan Trimble, President and CEO of Skyharbour, stated: ‘We are thrilled to close this major transaction for Skyharbour, and to embark on the next chapter of exploration at Russell with a multi-billion dollar strategic partner and large shareholder in Denison Mines. With up to $61.5 million in combined project consideration contemplated, we are confident that this strategic agreement will expedite the discovery process at the Project while minimizing equity dilution for our shareholders. Based on initial technical meetings and strategy sessions with Denison, we are excited about the combined exploration options for the near term. Russell is one of the more prospective exploration projects in the Athabasca Basin proximal to existing and developing mines including Denison’s Pheonix deposit at Wheeler River. Denison will also be able to provide considerable insight and experience as we jointly advance Russell. Lastly, we now enter the new year with a healthy treasury of over $11 million to fund our exploration efforts and corporate activities through 2026 while various partner companies fund exploration at numerous other projects in our portfolio.’

David Cates, President and CEO of Denison, further commented: ‘As Denison nears receipt of final regulatory approvals for the Phoenix In-Situ Recovery mine proposed for our flagship Wheeler River property, we are also making measured investments in our project pipeline – including our next development assets and high-potential exploration properties. Given its proximity to Wheeler River, Denison has had an interest in adding Russell to our property portfolio for much of my nearly two decades with the Company. This transaction achieves that objective by providing Denison with the opportunity to lead and participate in exploration efforts across four newly created joint ventures, which are designed to drive collaboration between Denison and Skyharbour’s technical teams. We are excited to build on our long-standing relationship with Skyharbour and accelerate the evaluation of this exceptional package of highly prospective ground.’

Transaction Details:

The consideration payment consisted of a $10.0 million cash payment, with $2.0 million paid upon execution of the Strategic Agreement and $8.0 million paid upon closing of the Strategic Agreement. An additional $8.0 million is payable in cash and shares by Denison on or before December 31 ^st , 2025 with a minimum of $2.0 million payable in cash.

It is anticipated that Denison will also be making use of the current exploration camp at McGowan Lake on the Project, which will continue to be operated by Skyharbour, and an administrative fee will be payable by Denison to Skyharbour. The claims comprising Russell are subject to various existing underlying royalties to other parties.

Skyharbour has received conditional approval from the TSX Venture Exchange for closing. The issuance of shares by Denison to Skyharbour remains subject to appliable exchange approvals.

Summary of Initial Joint Ventures:

Upon closing of the Strategic Agreement, Denison has earned an initial project interest in each of the four new Russell exploration projects including a 49% interest in the Wheeler North claims, a 20% interest in the RL claims, a 30% interest in the Getty East claims, and a 70% interest in the Wheeler River Inlier claims.

1. Wheeler North (51% SYH, 49% DML ; subject to additional earn-in options ) : The claims marked in yellow in the accompanying map represent 16,409 hectares over eight claims. The claims host some of the exploration targets located proximal to Wheeler River, including the Grayling and Fork Zones. Upon closing of the Transaction, Denison will have the option to increase its interest in Wheeler North to a 70% interest in these claims and Denison will become the operator of Wheeler North as described in more detail below.
2. Russell Lake or RL (80% SYH, 20% DML) : The claims marked in pink in the accompanying map represent 53,192 hectares over 16 claims. These claims are located north and west of Skyharbour’s Moore Project and host numerous exploration target areas including Christie Lake, NE Russell, Blue Steel, Taylor Bay, South Russell, and Kowalchuk Lake. In order to maintain its initial interest in RL, Denison has agreed to fund its pro rata share of up to a maximum of C$10.0 million in total project expenditures. Skyharbour will remain operator of RL.
3. Wheeler River Inliers (30% SYH, 70% DML) . The claims marked in blue in the accompanying map represent 608 hectares over two claims. These are inlier claims within Denison’s Wheeler River project hosting the West Russell and C-Block exploration target areas. DML will become operator of the Wheeler River Inliers.
4. Getty East (70% SYH, 30% DML ; subject to additional earn-in options ) . The claim marked in green in the accompanying map representing 3,105 hectares is host to the Little Man Lake exploration prospect. The claim borders Cameco’s Cree Zimmer property which holds its Key Lake operations to the south. Upon the closing of the Transaction, Skyharbour remains operator of Getty East; however, Denison has the option to become the operator and acquire up to a 70% interest in this joint venture as described in more detail below.

Denison Earn-In Options:

The Earn-In Option Agreements grant Denison an option to earn additional interests in Wheeler North and Getty East.

Phase 1: To earn an additional 19% interest in Getty East (increasing Denison’s ownership to 49%), Denison must incur $5.0 million in exploration expenditures at Getty East within 48 months of Closing, of which $1.5 million must be completed within the first 24 months of Closing.

Phase 2: To earn an additional 21% interest in Getty East (increasing Denison’s ownership to 70%), Denison must complete the requirements of Phase 1, plus incur an additional $10 million in exploration expenditures within 7 years of Closing. Upon completion of the Phase 2 earn-in option criteria, Denison will have the option to become the operator in this joint venture.

Russell Lake Uranium Project Overview:

The Russell Lake Project is a large, advanced-stage uranium exploration property totalling 73,314 hectares strategically located between Cameco’s Key Lake and McArthur River Projects, and adjoining Denison’s Wheeler River Project to the west and Skyharbour’s Moore Uranium Project to the east. The northern extension of Highway 914 between Key Lake and McArthur River runs through the western extent of the property and greatly enhances accessibility, while a high-voltage powerline is situated alongside this road.

Skyharbour’s New 80% Owned RL Project:

The claims making up the RL Project constitute over seventy percent of the original Russell project area and will continue to be explored by Skyharbour as the operator and 80% owner. Denison will acquire a 20% interest and has agreed to fund to maintain its pro-rata participation interest in the RL claims through December 31 ^st , 2029, or until such time that total expenditures on the properties have reached $10 million.

The RL claims have numerous highly prospective targets that Skyharbour will continue to advance. The Christie Lake target area contains basement-hosted uranium mineralization with historical drilling returning 0.17% U ₃ O ₈ over 0.4 metres at 436.4 metres depth in hole CL-10-03, hosted within a strongly hematized breccia. A prospective clay altered basement fault system runs throughout this area.

The Blue Steel target area comprises graphitic metasediments that were last drilled in 2008. The full extent of the graphitic corridor remains unknown and completely untested. Historical geophysics indicate potential faulting along this corridor, highlighting it as a priority area for follow-up work using modern geophysical methods to refine drill targets.

The Kowalchuk area, situated within the southern Russell claims, is another prospective area on the RL claims, with multiple inferred structural trends passing through it. This area has seen only limited modern geophysical coverage to date.

In addition to the aforementioned target areas, there are many kilometres of untested EM conductors on the RL claims underlain by rocks of low magnetic intensity, suggestive of the presence of prospective graphitic meta-pelitic basement lithologies typical of Athabasca-style uranium systems. With limited modern exploration conducted over the past 12 years, the RL claims remain underexplored and highly prospective for both expanding known mineralized zones and making new discoveries.
